 "title": "Booktics – Appointment Booking Calendar for Service Businesses <= 1.0.29 - Unauthenticated SQL Injection via 'customer_id' Parameter",
 "description": "The Booktics – Appointment Booking Calendar for Service Businesses plugin for WordPress is vulnerable to SQL Injection via the 'customer_id' parameter of the order creation REST endpoint in versions 1.0.4 up to, and including, 1.0.29. This is due to insufficient validation of the user-supplied parameter and lack of sufficient preparation on the existing SQL query. This makes it possible for unauthenticated attackers to append additional SQL queries into already existing queries that can be used to extract sensitive information from the database.",
